WEATHERQSTRIP.

SPECIFICATION forming part of Letters Patent No. 598,381, dated February 1, 1898.

Application filed June 23, 1897- To all whom it may concern.-

Be it known that I, JAooB M. MARoH, a citizen of the United States, and a resident of Narberth, Pennsylvania, have invented certain Improvements in Weather-Strips, of which the following is a specification.

The object of my invention is to construct a weather-strip with a movable section which can be applied to a window or door in the same manner as an ordinary weather-strip and which will be wedged tightly into the corner formed by the window sash and frame when the window is closed, yet will not bind upon the window-sash after it is opened, so that the window-sash can be readily raised and lowered.

In the accompanying drawings, Figure 1 is a perspective View of my improved weatherstrip. Fig. 2 is a sectional view showing a portion of the window-frame with the windowsash closed and the movable portion of the weather-strip forced into the corner. Fig. 3 is a view similar to Fig. 2, with the exception that the window-sash is raised and the removable portion of the weather-strip is released from the control of the sash. Fig. 4 is a view showing a window frame and sash with my invention adapted thereto, and Fig. 5 is a View of a modification.

As shown in Fig. 1, A and A are two sections of the strip secured together in the present instance by felt B, forming aloose hingejoint I). The strip A is secured to the frame D of the window in any suitable manner, preferably by screws, and the strip has a beveled edge a, against which rests the beveled edge a of the strip A, and the end of the strip A is blunt, as shown,'so that it will have a limited movement past the end of the strip A.

On the strip A is a projection or shoe F,

which is secured to the strip in the present instance by screws f. This shoe is beveled at top and bottom.

0n the sash D of the window is a projection d, in the form of a roller in the present instance, secured to the sash by a screw (1. This roller is so set in respect to the movable section A of the strip that when in the act of closing the window the roller will ride upon the projection F of the strip A and will tend to force the strip toward the window-frame;

but as the section A of the weather-strip has an inclined surface a, upon which the strip A rides, the tendency will be to force the strip A into the corner formed by the window and the strip A, thus forming a tight joint and preventing the ingress of air between the strip A and the window-frame. The felt or other material which binds the two strips A A together prevents the air from escaping through the passage formed by the two strips if anything should lodge in between the strips; but ordinarily these strips fit neatly. l

While I preferably insert the felt B or other material in the grooved face of each section, as shown in Fig. 1, it may be simply cemented upon the sections, as shown in Fig. 5, and the projection F may be formed itselfof the same material as the strip is made or may be a detachable piece, as shown in Fig. 1.

I claim as my invention- 1. The combination of a pair of strips having right-angled faces, one for bearing against the window-frame and the other for bearing against the sash, said strips having abutting beveled faces forming an acute angle with the faces which bear against the window frame and sash and means for forcing the sash-strip against the frame-strip as the sash is moved into the closed position, substantially as described.

2. The combination of a pair of strips having right-angled faces, one for bearing against the window-frame and the other for bearing against the sash, said strips having abutting beveled faces forming an acute angle with the faces which bear against the window frame and sash and extending to the inner edge of each strip and flexible material applied to the right-angled faces of the strips and providing a loose connection between them, substantially as described.

3. In a two-part weather-strip having a fixed and a movable section, said movable section being loosely connected to the fixed section at its inner edge and having a shoe at the back, a projection on the window-sash adapted to rest upon the shoe when the window is closed forcing the movable section into the corner formed by the window-sash and the fixed portion of the weather-strip.

.4. The combination of a weather-strip having a fixed section with a beveled edge, a wind0w-sash and the fixed portion of the IO movable section with a beveled edge resting Weather-strip, substantially as described.

upon the beveled edge of the fixed section, a In testimony whereof I have signed my strip of felt or other suitable material formname to this specification in the presence of ing a hinge and a bearing-face, one or more two subscribing Witnesses.
